NVD Description
Note: Versions mentioned in the description apply only to the upstream incus package and not the incus package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
Incus is a system container and virtual machine manager. Prior to version 7.2.0, the record-output parameter of the /instances/$name/exec endpoint stores the output of the command in the exec-output directory of the instance. If exec-output is a symlink, file named exec_UUID.stdout and exec_UUID.stderr can be written to an arbitrary location where the .stdout file will contain arbitrary content. This behavior can be abused for arbitrary command execution. Version 7.2.0 contains a patch.
